This. invention relates .to refrigerators and.

used in the production of ice creams, sherbets and the like.

. A further object is to-provi'dev meansfor Aaccomplishing the aforesaid results witlrput the use of electrical or mechanical devicesand merely by the congeal-ing inuence of the ice, ice and salt, or other refrigerant used for the preservation of the articles of food kept in the refrigerator.

, Other objectsof the invention are to be found in details of construction and anovel arrangement of parts' as will be disclosed in the course of the following description.

An embodiment ofthe invention has been -shown in the accompanying drawings in which like characters of reference designate corresponding parts throughout thel views and in which l v Figure 1 represents a perspective View ofa refrigerator made in accordance with my invention,

The refrigerator or ice box15 s own in' Figure 1, comprises a food chamber 6 and an ice Achamber 7 separated from each other by a vertical partition 8. The walls of the refrigerator are as usual made of suitable insulating structures and the ice chamber is lined with metal as indicated at 9.

Access to the food chamberis had by means' of a door 10 in the front of the refrigerator and the refri erantused for coolin the'food, is placed in te ice chamber throug an o eninin the top of therefrigerator closed y a -with the liquid su My invention consists, br-iey, in placing 1ns1de-the'1ce compartment, `one or more-re-v ceptacles adapted to contam water or other liquids, or mixtures used in making ices,sherl bets andthe like. The receptacle or. receptacles are Sdplacedv that they are fully subjected to thecooling influence of the refrigerantwithwhich the ice compartment is filled, and the receptacles are arranged with r ference to a door in the front of the refrigegtor so that they -mI ybe separately-remove u or replacedwhen the door 1s opened.

-The method of supporting the receptacles as illustrated in the drawings is preferred by, reason of its simplicity and practicability, but it is to be understood that variations in the construction of the -supporting meansand the; arrangement of the receptacles may bel i.

of. 'Il

made without departing from the Ispirit the invention.

i The receptacles are provided in the form of tra-ys 13 provided at their front end with handles 14 to facilitate their removal and replacement. VEach tray is slidably supported i in an individual box 15', the open front end of which is normallyA4 closed by thefront endof thev respective tray.

Grids 16 made of Ametal strips intersecting one another at right angles, may be loosely placed in the trays to divide the frozen con` tents thereof into small cubes or blocks which vcan be separately removed. The boxes and their respective trays, ,with or without thel grids, constitute the freezing units and it will be readily apparent that any desired number of these units may be used within thecapacity of the ice chamber. The various units in superposed relation to each other, are sus ended in the ice chamber by means of' a. ske eton frame 17 which is fastened tothe side walls of the compartment f and which is provided with a hollow domeshaped roof 18 to protect the freezing units l from the falling ice while the chamber is be.

ing filled. The units are preferably spaced 7 i from-each other to-provide brine-passages 22 between them. v Anopening 20 in the front of thechambe-r corresponding in size to the freezing appli# ance, is normally'closed'by a door 19 of insulating structure. It will be seen that when this door is opened all of the units are accessiblel for the removal or replacement of their trays so that the trays may be separately filled their -frozen contents removed for use whenever desiredn The grids divide the ice in the trays into,

blocks or cubes Whichrnay be separately removed. The refrigerant used in the ice chamber preferably consists of a mixture of @racked ice and salt as indicated by the reference 'numeral 2l, and owing to the ar rangement of the freezing appliance in the ice chamber as hereinabove described, the units thereof are on all sides except that facing the opening in the front of the refrigerator subjected to the cooling influence of the refrigerant.

rllhe trays are spaced from the top, side, and rear-end-Walls of the respective boxes to provide for air spaces Whichai'd in congealing the contents' of the trays and in keeping them in a frozen condition.

Having thus described my invention, What il claim and desire to secure by Letters Patent 1s ll claim:

lin a refrigerator havin@- an ice-chamber, a freezing element in the flamber in spaced relation to the Walls thereof, comprising a skeleton frame, including a hollow roof- 1ne1nber,.boxes in the frame, sliding trays in the boxes, and a door in a Wall of the refrigerator, affording access to the boxes. v

in testimony whereof ii have affixed my signature.
